Foxboro ™ DCS Compact FBM201 Analog Input Interface Module

Foxboro ™  DCS Compact FBM201 Analog Input Interface Module

Product Core Overview and Features

1. Core functions and positioning

Belonging to the Compact 200 Series I/O subsystem (see document PSS 41H-2COV for details), it has 8 independent analog input channels, each supporting a 2-wire 0-20 mA DC input, enabling interface conversion between on-site sensor signals and FCP (Field Control Processor).

Electrical compatibility with standard HART signals, suitable for the acquisition and transmission of analog signals in industrial automation scenarios.

2. Key characteristics

Specific content of characteristic categories

Isolation performance: Galvanic isolation is achieved between each analog input channel and other channels or ground to avoid signal interference

The accuracy guarantee adopts sigma delta data conversion technology (single channel independent conversion), generating a new reading every 25ms; Support configurable integration period for filtering out process noise and power line frequency noise (improving accuracy through average output)

Compact rugged design with environmental adaptability and physical protection of ABS shell; Adapt to G3 level (harsh) environments defined by ISA Standard S71.04

Easy to maintain installation on the Compact 200 series base plate, fixed with 2 screws; Support hot plugging (no need to remove on-site device wiring, power or communication cables when replacing modules)

The front of the status monitoring is integrated with red/green LED indicator lights, which intuitively display the operating status of the module

Detailed specification parameters

1. Functional specifications

Specification category specific parameters

The communication interface communicates with the associated FCM (fieldbus communication module) or FCP through a redundant 2 Mbps module fieldbus; Support A/B dual path switching, automatically switching to the active path in case of single path failure

Input protection current limit: conventional design ≤ 40mA, short circuit ≤ 100mA; withstand 600VAC (1 minute, not long-term applicable); Prohibited access to voltages greater than 30VAC/60VDC (violating electrical safety regulations and posing a risk of electric shock)

Power requirement input voltage: 24 VDC redundant input (+5%/-10% fluctuation tolerance); Power consumption: 7W; heat dissipation: 4W

The calibration requirement module and terminal components (TA) do not require calibration, reducing maintenance costs
